What a great resource. As someone who’s been making websites for 30 years, it’s amazing to still be picking up some of the basics. Though to be fair many of these didn’t exist back then.

I’ll be using this to add some extra tags to my pages.

It looks like there are some features noted as “required” that are actually required by the spec (e.g. a title tag), and others that are required by opinion (e.g. https) so there’s an element^ of pragmatic best practice being recommended.

I find it curious that setting a colour hint for the browser is recommended. I’m one for letting the browser look as vanilla as possible and letting my pages do the talking.

^Pun not intended, blink and you’ll miss it
